Estimating how long ago two species split up is a difficult task when only contemporary data is available. I examine how reliably speciation times can be estimated by a method based on the distribution of pairwise differences between extant DNA sequences. For these tests I use artificial molecular data obtained from an individual-based evolutionary model. This approach enables comparison of actual speciation times with estimates based on analyzing the distribution of DNA differences and on classical phylogentic reconstruction.
